Large gearsmachined to drawing.
Linyao Machinery is a custom plant in Luoyang, China, producing large gears, shafts and non-standard parts. We machine to drawing for mining, metallurgy, petroleum, chemicals, shipbuilding and wind power. An 8 m gantry mill and 12 m lathe in-house: one-offs to small batches, with testing at every stage.

In Luoyang,
drawings become parts.
Linyao Machinery manufactures large mechanical parts and non-standard components to customer drawings: gears, gear shafts, shafts, sprockets, mining parts, bearing housings, castings and forgings, and hydraulic cylinders.
From one-off prototypes to small-batch delivery, material, heat treatment, machining and inspection run under one roof; export parts are rust-proofed and packed for their destination. We work to drawings or samples, and can agree on a drawing with you based on the operating conditions.

Drawing, material, tolerance — align all three, and the part fits.
It has to mesh
before it turns.
A gear is never judged on its own. Module, tooth count and center distance have to agree before a pair runs smoothly. Linyao machines gears and shafts as a set, checking tooth form, tooth lead and journal datums on the same route.
